To my knowledge, you will earn skill points more than attribute points. Like in a videogame, you will earn skill points with the more experience you get in each field. Obviously, you will start with fumbling and shiz, and the more you do it, the more proficient you get at it. So I'd say each time you successfully complete a task in each skill (and hell well you do it), you will gain a point or two, depending on how Night and I feel about whether it was a good enough job to earn a skillpoint. I'll have to double-check with Night, though.
